Dan,
The roller cam will free up some HP, keep it small, 1,500 to 5,200 rpm.I would keep the stock heads for the street . A good example was my 91 5 liter coupe. stock it went 14.4 ET, with 3.08 gears. I ported the heads,matched the intake gaskets, 180* termostat, 12* initial timing,K&N filter, it went 13.8's at shifting at 5,200 rpm with a shift light, the factory tach is 300 rpm slow! I went to 3.55 gears and BIG mistake for the street, now I have no traction and the car lights up at 1/2 throttle so I'm losing the stop light drags. At the track I'm 14.2 on and off the gas tires slipping. With drag radials I went 13.5 but still not good on the street. You need a simple combo that doesn't overpower your traction.
Good Luck,
Perry.
